3 3 Ordförandes ord Hej SSBA medlemmar! Ida Maria Sintorn Vilken intensiv SSBA vår det har varit! Jä ebra och välarrangerat SSBA i Göteborg, och så SSDL och SCIA i Norrköping med massa intressant inbjudna talare och presenta oner a lyssna på från bekväma biofåtöljer. Alla arrangemang har erbjudit möjligheter för sociala ak viteter och nätverkande inte minst alla intressanta diskussioner kring postrar. Detaljer från dessa tre stora föreningsevent och fler där ll samt blandat små och go som vanligt finner ni längre fram i nyhetsbladet. Något som inte står i dessa beskrivningar men väl värt a nämna är a det på föreningens årsmöte under SSBA symposiet togs beslut om a erbjuda sponsring av deltagaravgi en för SCIA för föreningens doktorander. Det resulterade i a 19 av våra doktorander sökte och fick bidrag för SCIAs registreringsavgi vilket ju både gynnade våra doktorander och vår SCIA konferens bra förslag Ingela Nyström! Apropå SCIA så arrangerade vi under konferensen i Norrköping en diskussionssession om fram den för SCIA vik gt och intressant. Det blev en livlig diskussion med många bra förslag och kommentarer om vad som varit bra och vad man kan göra för a förbä ra och förstärka konferensen y erligare. Några punkter som kom fram var: konferensen är bra, den behövs som komplement ll trenden med jä ekonferenser, den är vik g för regionalt nätverkande. Kort och go : SCIA bör finnas kvar och behöver därför växa lite och kanske även utvidgas ll a omfa a e större basområde (Norden eller norra Europa kanske?) och annonseras bä re. Anteckningar från diskussionen finns längre fram i det här nyhetsbladet och har också vidarebefordrats ll vår finska systerorganisa on som står som värd för SCIA Jag hoppas a ni medlemmar fortsä er a komma med åsikter och förslag i frågan om SCIA, våra symposier mm. E ypperligt llfälle a göra det är a delta i SSBA internatet 5 6 november (se no s om internatet längre fram). Hoppas vi ses där! Slutligen, för er som inte var med på SCIA åk ll visualiseringscentret i Norrköping för a färdas vidare ut i rymden en fantas sk upplevelse! Glad sommar allihop!

4 SSBA 2019 Report Axel Andersson 4 SSBA2019 took place in Gothenburg between 18 and 20 March. The conference began with a PhD day, where doctoral students from different Swedish universi es met to eat porridge, drink tea, network, and discuss relevant topics. The event was arranged in Chalmers Hus; a 200 year old building, and former residence of Chalmers University of Technology s founder William Chalmers. The PhD day was also my first working day as a doctoral student. I must admit, it felt quite flashy to start off my coming years of studies with a luxurious breakfast in a grandiose 19th century house. The PhD day con nued with visits at two interes ng image analysis linked companies: Irisity and SmartEye. Irisity showed the latest in camera surveillance technology, and shared interes ng words about star ng and running a company. At Smart Eye, we tested a variety of applica ons related to eye tracking and had the opportunity to talk with their researchers and developers. Both companies gave a very good impression. The PhD day ended with the conference welcome recep on, which also took place in the luxurious Chalmers house. During the next two days, the symposium was in full swing. The sessions where filled with presenta ons from PhDs, researchers and industrial representa ves. The invited speakers presented topics on Segmenta on without Supervision (Yuri Boykov) and Spa al Percep on for Mobile Robots (Stefan Leutenegger). The tradi onal conference banquet took place on the River Restaurant, a restaurant located on a pier out in the Göta Älv. Overall, it was a real pleasure to a end to SSBA. For me, the conference was both educa onal and entertaining. It was a very amicable, almost familiar atmosphere throughout the en re conference. I'm already looking forward to a ending in the coming years!

5 Call for Interest SSBA internat, November 5 6, SSBA internatet är e utmärkt llfälle a höja blicken från din förestående ansökan, ar kel eller leverans, och istället llsammans verka för a svensk bildanalys står ännu starkare om några år än vad vi gör idag: a både företag och universitet har en kompetensbas a rekrytera från, a bidragsgivare förstår värdet av forskning på området a vi fortsa har en utbildning och forskning i världsklass. Målet med internaten är a ta fram planer för a genom SSBAs nätverk driva strategiskt vik ga bildanalysfrågor i och för Sverige. Internatet organiseras huvudsakligen som diskussionsgrupper med olika ingångsvinklar och med målet a ta fram konkreta planer, stora som små, som är rimliga a realisera det kommande året. Sedan digare har vi delat upp våra insatser i tre fokusområden: utbildning, forskning och industri. Internatet har även den direkta effekten a utöka nätverket för deltagarna och SSBAinternaten brukar förläggas ll ställen som uppmuntrar ll sociala ak viteter; internatet har arrangerats på Lovik, Lidingö (2016) och Ystad Saltsjöbad (2017). Exempel på e lyckat resultat från internaten är SSDL symposiet som i år arrangerades för tredje året i rad. Tänkbara diskussionsämnen för nästa SSBA internat: 1. De olika Masterprogram med inriktningar som är relevanta för SSBA, t.ex. bildanalys och maskininlärning, som håller på a u ormas på olika håll i Sverige 2. Industrins syn på u ormning av utbildningsprogram/kurser. Stämmer utbildningarna med industrins behov och önskningar och/eller hur kan industrin påverka? 3. Hur vi kan utvidga vårt nätverk och samarbeten med våra grannländers systerorganisa oner för a stärka vårt ämnes varumärke y erligare? Anmäl ert intresse för a delta på årets SSBA internat den 5 6 november med epost ll styrelsen ssba@ssba.org.se. Kom gärna med förslag på andra/y erligare diskussionsämnen!

6 S S B A K T U E L LT n r 6 0 juni 2019 Soapbox Science Elisabeth Wetzer Roy Francis On May 25, 2019 Uppsala s very first Soapbox Science event took place in front of the University Library Carolina Rediviva a er last year s success in Umeå as well as its very posi ve interna onal re cep on for many years. The event is a public outreach pla orm which gives a stage (in form of a soapbox) to women in science to promote the research they do and why they think it s fascina ng. There are no Powerpoint slides, no microphones, but the scien sts can bring any equipment they can think of to demonstrate and give insight to their daily discoveries. Uppsala s event featured women scien sts from the Swedish Uni versity of Agricultural Sciences (SLU) as well as Uppsala University. Not just one, but two speakers came from the field of Image Analy sis & Processing Leslie Solorzano and Elisabeth Wetzer from the Centre for Image Analysis. The interest of passers by and listeners of the event was big and led to many ques ons and discussions ranging from how Instagram filters work, over how computers can detect cancer on images to guessing if images were real or GAN generated! 6

8 SSDL 2019 Report 8 Ankit Gupta The third Swedish Symposium on Deep Learning(SSDL) arranged by the Swedish Society for Automated Image Analysis was held in Norrköping during June The symposium was dedicated to the latest trends and developments in deep learning. It took place in Norrköping Visualiza on center C of Linköping University in co loca on with SCIA The symposium featured keynote speakers from Google, KTH Royal Ins tute of Technology, Radboud University Medical Center and Erasmus MC. The topics of the keynotes varied from computer vision and natural language processing to biomedical imaging and computa onal pathology. Overall, 20 papers were accepted and 7 of them were selected for oral presenta ons. The papers featured a diverse variety of applica ons of deep learning in various fields such as CT/MR imaging, in vehicle ac vity, word spo ng and, aerial imagery. The par cipants came mainly from academia and industry in Sweden.

9 SCIA 2019 Report 9 Emanuel Sanchez Aimar The twenty second Scandinavian Conference on Image Analysis (SCIA) was held at the Linköping University Campus in Norrköping, Sweden, nearby the twin city of Linköping, where the first SCIA took place almost 40 years ago. And s ll, it has been the first me I had the privilege to be present at the conference, lucky enough to a end on my first week as a PhD student. Day one of SCIA began immediately a er the end of the co located event SSDL 19. For three days, I had the opportunity to a end to several oral sessions, poster spotlights (3 minute talks), poster sessions and keynotes given by renowned speakers. I especially enjoyed poster sessions during coffee breaks, or fikas, as they are known in Sweden. Not only it was very interes ng to learn about the research breakthroughs that PhD students are doing in Scandinavian countries, but also allowed me to chat with my newly acquainted community, while immersed in Norrkoping Campus' beau ful landscape. Deep learning is now ubiquitous in computer vision and image analysis, and its influence was very no ceable in a large majority of research papers. The conference covered a wide range of topics such as recogni on, segmenta on and 3D vision; as well as many exci ng industrial focused applica ons. I would like to make a special men on to the large number of accepted ar cles in medical imaging, that are leveraging state of the art deep learning techniques, with the aim of improving health care. Each day, the climax of the event would be an exci ng keynote, presen ng highly relevant topics such as: Strategies to leverage temporal informa on in dynamic scene understanding (Laura Leal Taixé). Capturing 3D models of the world from video (Lourdes Agapito). Efficient signed graph par oning for computer vision problems (Fred Hamprecht). All keynotes were well reasoned and had excellent standards, even providing the audience with details of ongoing research work. As part of the social events, I was amazed by Norrköping s Visualiza on Center, where we went into a journey through space and me, in which we vividly relived the Apollo 17 moon landing and explored the solar system, as part of an immersive 3D exhibi on. Last but not least, during the conference dinner I was introduced to several delicious Swedish dishes, followed by a musical performance by the local band Lorator, who astonished us with a show of special effects produced by two musical tesla coils, sparkling to the beat of the music. Even though the exact loca on for SCIA 21 is s ll a mystery, and without discarding a trip in ferry between Sweden and Finland as a candidate venue, I am looking forward to a ending my second SCIA, for a couple of days full of s mula ng research ideas, amicable people and amusing social ac vi es.

11 Future of SCIA Ideas 11 At SCIA 2019 we had a plenary session where we invited sugges ons from the audience on how to modernise the conference. Below we have listed the sugges ons and comments received. Some are sugges ons from single a endants and do not represent consensus. Some ideas we put to a vote, these are more representa ve. Proceedings: IEEE instead of Springer? CVF proceedings? (we asked for SCIA2019, and CVF said maybe next me ) Adver sing: Booth at big conferences? (this is expensive) Encourage par cipants to adver se the conference? Adver se on linked in? SCIA facebook page? Misc: Invite Nordic thesis winner? Format: Annual SCIA? Vote: mixed Add workshops, and tuorials SSDL together with SCIA. Was this a good idea? Vote: half for, others did not a end. Scandinavian symposium on deep learning? Vote: mixed, majority posi ve. Other focus topics as well, e.g. geometry? Keep the spotlight format? Vote: good, keep More posters, also for orals? (we invited orals to have posters this year, perhaps we should use coercion at next SCIA?) Nectar sessions as on GCPR? (re presenta on of CVPR/ICCV/ECCV work as SCIA posters without review or publica on) Rename SCIA to Nordic conference on image analysis? Vote: Mixed, majority posi ve.

12 12 Network of EUropean BioImage AnalystS Conference 2019 (NEUBIAS) Report Nadezhda Koriakina The 3rd NEUBIAS conference is the first conference I a ended as a PhD student. This year it was held in the heart of Europe, Grand Duchy of Luxembourg. The network aims to promote the mutual communica on between specialists in life science and specialists in computer science, and nearly 300 par cipants were able to share experience and knowledge on various topics. During the conference, a wide range of ac vi es was offered: taggathon, training schools, workshops, speaker sessions, special sessions, poster lunches. I presented my early results in a poster and had a chance to communicate with other researchers with different background and from different countries. I found it as a rewarding experience, since I had a chance to listen to opinion of researchers about my work as well as understand the problems of others. Talking about speaker sessions, I would say it was a good balance between life science and image analysis topics, and both experienced and early career speakers were presen ng their research. My colleagues were ac vely involved in giving talks, presen ng posters and so ware, and I hope this trend will remain for the next years. Overall, I like the a tude of the network to share the knowledge in both theore cal and prac cal aspects, promo ng open source so ware tools and similar. I envision that an important goal of the network and rich program of the conference would a ract more and more people.
